How long before Flex Caulk can get wet?
When sealing cracks, joints, or gaps, timing matters, especially if there’s rain in the forecast or moisture in the area. So how long should you wait before Flex Caulk can get wet?
The answer depends on which type of Flex Caulk you’re using and the conditions you’re applying it in.
Flex Caulk Silicone must be applied to a completely dry surface and should remain dry until it reaches full cure. Once cured, it is highly durable and weather-resistant, but needs a dry start for the best results. Flex Caulk requires 12 to 24 hours to fully cure after application. That means it's not ready to face water, weather, or regular use until the curing process is complete. Exposing uncured Flex Caulk Silicone to moisture can weaken adhesion and compromise the seal.
Flex Caulk Hybrid is the better choice if you're dealing with damp surfaces, high humidity, or unpredictable weather. It can be applied to wet or even underwater surfaces, and still cures into a strong, waterproof seal. It is ideal for rainy conditions and emergency repairs.
For optimal results, always follow label directions and make sure your caulk has time to fully cure before water exposure. Whether you’re sealing windows, trim, or tile, Flex Caulk is ready to handle the job. To learn more about Flex Caulk Hybrid and Silicone, click here.
